2013-06-07LDAP: store FQDNs for trusted users and groupsJakub Hrozek1-2/+10
Because the NSS responder expects the name attribute to contain FQDN, we must save the name as FQDN in the LDAP provider if the domain we save to is a subdomain.
2013-06-07LDAP: new SDAP domain structureJakub Hrozek1-8/+8
Previously an sdap_id_ctx was always tied to one domain with a single set of search bases. But with the introduction of Global Catalog lookups, primary domain and subdomains might have different search bases. This patch introduces a new structure sdap_domain that contains an sssd domain or subdomain and a set of search bases. With this patch, there is only one sdap_domain that describes the primary domain.

2013-05-02LDAP: always store SID if availableSumit Bose1-21/+28
Currently the string representation of a SID is only stored in the cache for debugging purpose if SID based ID-mapping is used. This patch unconditionally stores the SID if available to allow SID-to-name mappings from the cache.
2013-04-19LDAP: do not invalidate pointer with realloc while processing ghost usersJakub Hrozek1-3/+13
https://fedorahosted.org/sssd/ticket/1799 One peculiarity of the sysdb_attrs_get_el interface is that if the attribute does not exist, then the attrs array is reallocated and the element is created. But in case other pointers are already pointing into the array, the realloc might invalidate them. Such case was in the sdap_process_ghost_members function where if the group had no members, the "gh" pointer requested earlier might have been invalidated by the realloc in order to create the member element.

https://fedorahosted.org/sssd/ticket/1755 sdap_find_entry_by_origDN() may return ENOENT in these non-error scenarios: If a member is out of scope of configured nesting level, sssd produces few noise lines indicating failure. The worse case is when a member is outside of configured search bases. In this case we save the group with incomplete membership,
2013-01-28nested groups: fix group lookup hangs if member dn is incorrectPavel Březina1-0/+24
https://fedorahosted.org/sssd/ticket/1783 When dn in member attribute is invalid (e.g. rdn instead of dn) or it is outside of configured search bases, we might hit a situation when tevent_req is marked as done before any callback could be attached on it.

2013-01-09AD: Add user as a direct member of his primary groupJakub Hrozek1-8/+109
In the AD case, deployments sometimes add groups as parents of the primary GID group. These groups are then returned during initgroups in the tokenGroups attribute and member/memberof links are established between the user and the group. However, any update of these groups would remove the links, so a sequence of calls: id -G user; id user; id -G user would return different group memberships. The downside of this approach is that the user is returned as a group member during getgrgid call as well.
2013-01-09AD: replace GID/UID, do not add another oneJakub Hrozek1-5/+3
The code would call sysdb_attrs_add_uint32 which added another UID or GID to the ID=0 we already downloaded from LDAP (0 is the default value) when ID-mapping an entry. This led to funky behaviour later on when we wanted to process the ID.

2012-11-28idmap: Silence DEBUG messages when dealing with built-in SIDs.Michal Zidek1-27/+34
When converting built-in SID to unix GID/UID a confusing debug message about the failed conversion was printed. This patch special cases these built-in objects. https://fedorahosted.org/sssd/ticket/1593
2012-11-20LDAP: Only convert direct parents' ghost attribute to memberJakub Hrozek1-3/+21
https://fedorahosted.org/sssd/ticket/1612 This patch changes the handling of ghost attributes when saving the actual user entry. Instead of always linking all groups that contained the ghost attribute with the new user entry, the original member attributes are now saved in the group object and the user entry is only linked with its direct parents. As the member attribute is compared against the originalDN of the user, if either the originalDN or the originalMember attributes are missing, the user object is linked with all the groups as a fallback. The original member attributes are only saved if the LDAP schema supports nesting.

2012-11-19LDAP: Fix saving empty groupsJakub Hrozek1-2/+4
https://fedorahosted.org/sssd/ticket/1647 A logic bug in the LDAP provider causes an attempt to allocate a zero-length array for group members while processing an empty group. The allocation would return NULL and saving the empty group would fail.
2012-11-19LDAP: Allocate the temporary context on NULL, not memctxJakub Hrozek1-1/+1
Allocating temporary context on NULL helps vind memory leaks with valgrind and avoid growing memory over time by allocating on a long-lived context.

2012-11-01LDAP: Fix off-by-one error when saving ghost usersJakub Hrozek1-1/+1
The ldb_val's length parameter should not include the terminating NULL. This was causing funky behaviour as the users were saved as binary attributes. https://fedorahosted.org/sssd/ticket/1614
2012-10-12Create ghost users when a user DN is encountered in IPAJakub Hrozek1-37/+276
The IPA has a defined directory tree structure that allows us to guess the username from a DN without having to look up the DN in LDAP. https://fedorahosted.org/sssd/ticket/1319

2012-06-13Fix an issue in ghost usersJan Zeleny1-75/+47
There was an issue with ghost members in nested groups. Consider a scenario with two groups A and B, B being member of A and having some ghost members. In such case SSSD stored both groups, then added membership between them and then added ghost members to the group B. The problem was that adding ghost members to group B didn't propagate these ghost members to group A. This functionality could have been solved by memberof plugin but the logic is far more complicated that changes this patch introduces. The change is simple: add ghost members at the same time as the group is created, even if groups are supposed to be stored in two passes. That way ghost members will be present at the time A -> B membership is created and they will be propagated as expected.
2012-06-13LDAP: Auto-detect support for the ldap match ruleStephen Gallagher1-0/+1
This patch extends the RootDSE lookup so that we will perform a second request to test whether the match rule syntax can be used. If both groups and initgroups are disabled in the configuration, this lookup request can be skipped.

2012-05-31Ghost members - support in LDAP providerJan Zeleny1-186/+286
The original approach was to store name and original DN in an object in sysdb. When later referenced as member of a group, it was retrieved by its original DN and the correct information about its sysdb DN was stored in the group object which referenced it. The new approach doesn't use fake user objects, therefore this information has to be reached differently when constructing group memberships. The approach is to store all users to a hash table where original DN is used as the key and username as value. When constructing group memberships, the name is retrieved from this hash table instead of sysdb. This hash table is constructed when retrieving user objects from LDAP server - if the user is not present in sysdb, it is automatically stored in the hash table. Another situation is for rfc2307. Because there is no nesting there, we can construct the SYSDB_GHOST attribute directly and therefore don't need a hash table of ghost users.

2012-05-10LDAP: Handle very large Active Directory groupsStephen Gallagher1-17/+37
Active Directory 2008R2 allows only 1500 group members to be retrieved in a single lookup. However, when we hit such a situation, we can take advantage of the ASQ lookups, which are not similarly limited. With this patch, we will add any members found by ASQ that were not found by the initial lookup so we will end with a complete group listing. https://fedorahosted.org/sssd/ticket/783
2012-05-10LDAP: Add attr_count return value to build_attrs_from_map()Stephen Gallagher1-6/+8
This is necessary because in several places in the code, we are appending to the attrs returned from this value, and if we relied on the map size macro, we would be appending after the NULL terminator if one or more attributes were defined as NULL.
